Title: Pneumatically operated vehicle disc brake - has wear rate of pads reduced by using different pads for normal and emergency braking
Inventor: RAUSCHER WOLFGANG DIPL ING
IPC: F16D55/22
Filed: 1977-10-07
Abstract: A disc brake is provided with two sets of brake pads whose coefficient of friction and wear resistance are different. A compressed air supply and a foot operated two stage valve are used to apply the brake force to the friction pads. For normal braking, the friction pads with higher wear resistance but lower brake efficiency are applied. For an emergency stop, the second set of brake pads with a high friction coefficient are appied. The durability of the friction pads for normal braking is thus considerably increased.

Title: Bacon rind peeling machine - with auxiliary slitting blades for processing long-storage bacon
Inventor: SCHILL HERMANN
IPC: A22C17/12
Filed: 1978-04-18
Abstract: A machine to remove the rind from sides of bacon has a peeling balde downstream of the gap between a tension roll and a multi-ring back-up roll. An auxiliary de ice carries several slitting blades which enter between the rings of the back-up roll and produce slits in the bacon. This enables the machine to process not only fresh bacon but also sides which have been stored for some time and have therefore acquired a round shape. The bacon material is thus easily flattened without excessive pressure.

Title: PWM loudspeaker drive circuit - is regulated by deriving feedback from induced EMF during intervals between pulses
Inventor: TROPF HERMANN DIPL ING
IPC: H04R3/00
Filed: 1978-06-29
Abstract: High performance of electrodynamic transducers, esp. loudspeakers, is obtained by deriving a control signal without using special transducers or mechanical modifications. The signal is proportional to the speed of the membrane, as indicated by the emf induced during the pauses in the pulse width modulated signals. The switches (3), e.g. V-MOSTS trigger the bridge (1) of which the loudspeaker (2) forms one arm. The resultant voltage (Uz) and the signal voltage (Us) are fed to a differential amplifier (4). After filtering (5, 6) the output goes to the push-pull pulse width modulator (7) which triggers the switches (3).

Title: Annular nozzle for cutting torch - with extra mixing chamber and outlet for extra annular flame
Inventor: HENNECKE FRANZ
IPC: F23D14/54
Filed: 1978-07-22
Abstract: An annular nozzle for a torch to be used for cutting, welding or flame descaling operations with or without a central cutting oxygen channel has concentric heating gas and heating oxygen channels terminating in a mixing chamber with an annular outlet. The latter is surrounded by one or more concentric mixing chambers and outlets. The additional heating flame rings can be used to intensify the action of the inner flame ring, without any detrimental heat concn. A better heat distribution without fusing of the edges of a cut or other deformation is the result. Most benefits accure at low ambient temp. and high steels. The new torch produces less noise.

Title: Level indicator for conducting carbon powder containers - uses contact plate detector on probe flexed to displace deposits
Inventor: KLEMMER ADELHART
IPC: G01F23/24
Filed: 1978-10-30
Abstract: A level indicator for containers of electrically conducting material, e.g. carbon powder for rubber processes, has a rod-shaped probe projecting downwards into the container, which is often in a bunker or silo. The probe has a contact element at its lower end and is electrically insulated from the container walls. A flexible probe is used to enable deposits on the probe to be displaced by moving it in pendulum fashion and about a transverse axis. This eliminates false readings and insulation breakdown automatically, simply and without maintenance. The probe may be a suspension cable or feed screw with an insulation coating. The flat contact element is attached to the probe at one end, i.e. not at its centre of gravity, pref. at the apex of an isosceles triangle.

Title: Friction pad mounting plate on disc brakes - has leaf spring to provide radial location and radial force for friction pads
Inventor: TAMURA KOICHI
IPC: F16D65/097
Filed: 1978-12-19
Abstract: A disc brake has two brake pads (10, 11), between which the disc is rotating. Hydraulic brake cylinders (6, 7) are an integral part of the brake support yoke (1) and act directly on the friction pad mounting plates. A leaf spring (13) is located in the centre slot of the support yoke (1) and it produces a radial force which pushes the friction pads radially towards the brake disc. Bent lugs (10b, 11b) on the friction pad mounting plates engage the brake pistons (6, 7) so that the spring load on the brake pads is counteracted.
